 Tai Chi is a form of exercise that has been shown to improve psychological health. A systematic review of 40 studies found that regular Tai Chi, one hour to one year, significantly increased psychological well-being, including reduction of stress, anxiety, depression and mood disturbance, and enhanced mood in community-dwelling healthy participants and patients with chronic conditions. Seven observational studies also reinforced the beneficial association between Tai Chi practice and psychological health. However, definitive conclusions were limited due to variation in designs, comparisons, heterogeneous outcomes and inadequate controls. High quality, well-controlled, longer randomized trials are needed to better inform clinical decisions. This article was authored by Scott Tammy, Kupelnick Bruce, Rammel Judith and others.
